The basic RG270 and S370 seem to check out well in reviews..as quite similar.I've never tried these guitars but i'd say play em both back to back (a good Ibinhad dealer should have a large range for you to try)

My first "proper" guitar was an Ibanez RS120 (twin powersound humbuckers with coil taps)This was a budget Ibanez, one of the lower end ones - if not the cheapest.

I have had this guitar for 15 yrs now and despite the abuse it's had over the years it still sounds fine and not a single thing has gone wrong with it!!, a little generic sounding - ie; definitly not a strat,tele or les paul type sound, but a good approximation. Fine solid guitars,generally.

I think that the RG series holds it's value better generally as they are well known guitars,not sure about the S.

Hope you fine a good un :)
